We can even supply innovative stainless steel buildings to provide long-life, low-maintenance equipment housings for difficult-to-access or hazardous sites.
Portastor provides a first level of fit out, before liaising with original equipment manufacturers (OEMs) and other third-party suppliers to integrate all power, signalling and communication systems into your buildings, prior to delivery.

Secure traction power buildings

Portastor substations and switchgear equipment housings are used to house equipment supplying traction power to railway lines. Whether you need to supply AC power for overhead lines (OHLE) or DC power for the third rail on Southern zone networks, you can rely on Portastor to provide safe, robust e-houses for all transformers, rectifiers and switchgear.

Robust buildings for safety-critical equipment

When you need reliable, individually designed buildings to house safety-critical protection, signalling and communications systems, Portastor offers tried and tested solutions for re-locatable equipment buildings (REB),auxiliary electrical equipment (AEE) buildingsand signalling and communications equipment rooms (SER/CER). Your Portastor equipment housings will be designed to meet the rail sector’s stringent requirements for health and safety, materials selection, fire resistance and electrical engineering standards.
Portastor buildings are also used to house essential back-up power for signalling systems. These uninterruptible power supply (UPS) or power supply unit (PSU) rooms provide power to signals in the event of a mains power failure.

It's extremely beneficial for us to be able to complete the factory acceptance tests at Portastor, away from the live trackside site. It means the buildings arrive on location ready for rapid connection and final testing, significantly reducing the time, cost and risk associated with the trackside installation phase
